⁠Rust + Python Toolchain Image

⁠Overview

This Docker image provides a reusable Rust + CPython toolchain designed for projects that combine:

• Rust crates
• Python bindings via PyO3
• maturin-based build workflows

It is a base image, not an application image, and should be extended using FROM in service-specific Dockerfiles.

⁠Included Components

⁠Why Python Is Built From Source

Python is compiled from source to:

• Ensure correct PyO3 header/runtime matching
• Enable ABI3 forward compatibility
• Avoid distro-specific Python limitations
• Provide deterministic, portable builds

Build flags used:

• --enable-optimizations
• --with-lto
• --enable-shared

⁠Environment Defaults

The image sets:

PYO3_USE_ABI3_FORWARD_COMPATIBILITY=1
RUST_BACKTRACE=1
PYTHONUNBUFFERED=1
